FREDERICK W. SALMON, OF BURLINGTON, IOWA.

GOVERNOR.

Application filed April 22, 1907.

To all whom it may concern:

Be it known that I, FREDERICK W. SAL- MON, of Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Governors and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in governor for steam engines and other motors, and particularly to that class of governors now known to those skilled in the art as the pendulum or conical governor.

The object of the invention is to provide simple and readily operable means for adjusting the governor while at rest or in motion, whereby the speed of the motor may be changed, and the desired speed maintained, with but slight variation.

With this end in view my invention consists in the combinations of parts whereby the plane of revolution in which the balls re volve, may be varied with relation to the point of suspension of said balls.

My invention further consists in the parts and combination of parts as will be more fully explained and pointed out in the claims.

In the accompanying drawing Figure 1 is a view partly in section and partly in elevation of my improvement, and Fig. 2 is a view in perspective of the bearing which carries the spindle.

1 represents the column or standard, and 2 and 14 the sectional spindle, the lower section 14 passing through the bearing at the lower end of the column, and carrying at its lower end a beveled gear wheel 3 which meshes with a bevel pinion 3 on shaft 4, which latter in turn is usually driven from the main shaft of the engine by means of a belt and pulleys. Section 2 of the spindle is provided at its upper end with a head 5 to which are secured one or more (two in the present instance) arms 6 carrying at their outer ends the weights or balls 7, and these arms 6 are connected intermediate their ends to the spindle sleeve 9 by the links 8. This spindle sleeve is designed to be connected up to the cut-off mechanism or regulating gear of the motor by rods attached to the lower cross-arms 11, which latter rest and move in slots formed in the upper end of the standard 1. The center weight 10 is secured to or is formed with the sleeve at the upper Specification of Letters Patent.

end of the latter and tends to hold the sleeve in its normal or lowest position.

12 is a gag-pot which is used in connection with a piston coupled up with the sleeve 9, to prevent the governor from surging under extreme fluctuations of the load.

In Fig. 1 I have shown in full lines the governor adjusted for fast speed and have shown in dotted lines the positions of the parts adjusted for slow speed. One method of accomplishing this adjustment of the spindle and governor arms and balls, is by making the spindle of two telesco ic sections, the up per longitudinally movab e section 2 of which carries the governor arms, while the lower section 14 is cou led up by the bevel gear wheels 3 with sha 't 4. The lower end of sec: tion 2 is made-hollow or tubular, and fits over and slides on the upper end of lower section 14, the connection between the two sections 2 and 14 of the spindle being such that the upper section is free to move longitudinally on the lower section, but rotates therewith.

Secured to and embracing the section 2 of the spindle near the lower end of the latter is the collar 15 having a runway in its lower face. This collar is secured to the tubular section of spindle 2, by key 16, which in the present instance passes through the collar 15, section 2 of the spindle, and through an elongated slot in section 14 of the spindle, and operates to not only look the collar 15 to the upper section of the spindle, but also looks the two sections of the spindle a ainst independent rotary motion. The collar 15 thus secured to the upper section of the spindle rests upon a block 17 supported on the bearing 18. This block 17 is provided 011 its upper face with a runway which together with the runway on collar 15 forms an endless track for a series of balls, which form an antifriction thrust bearing supporting the upper section 2 of spindle. Bearing 18shown detached in Fig. 2*comprises a body and two diametrically disposed side arms, the latter being threaded at their outer ends as shown and engaging internal threads on the sleeve nut 19. The column 1 is slotted longitudinally at the part thereof embraced by the sleeve nut 19 for the passage of the threaded arms of bearing 18, and the sleeve nut 19 is free to turn on said column, but is restrained from longitudinal movement by shoulders shown in Fig. 1. The anti-friction bearing above described rests on bearing 18, and as the arms of the latter pass through longitudinal slots in the column 1, it will be seen that if the sleeve nut 19 be rotated by the hand wheel 20, secured thereto, it will operate to raise or lower the bearing 18, and thus raise or lower the upper section 2 of the spindle. This bearing 18 therefore supports the upper section 2 of the spindle, and as the lower section 14 of the spindle passes through the bearing 18 and into the tubular end of the up er section 2 of the spindle, it is evident tl iat a rotary movement of the lower section of the spindle, will be imparted to the upper section irrespective of the adjusted positlon of the latter. By this construction of parts, the spindle head 5 may be adjusted to any position intermediate its extremes, one of which is shown in full lines, and the other at 13 in dotted lines in Fig. 1.

It is a well known fact that a governor in the position shown in full lines will have to revolve at a higher speed to raise the spindle sleeve 11, than at any intermediate point between its position for fast speed, and its highest position indicated by the numeral 13, hence by adjusting the spindle longitudinally as described, the speed of the motor may be changed and the desired speed maintained with but small variation.

It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but,

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,

1. In a governor for motors, the combination with a standard, a rotating spindle composed of telescopic sections, one section of which is adapted to be moved longitudinally, of a thrust bearing supporting the longitudinally movable section and having laterally projecting arms threaded on their outer ends and, passing through slots in the standard, and a screw sleeve mounted on the standard and engaging the threaded ends of the arms of the thrust bearing.

2. In a rotary governor, the combination of a standard, a spindle composed of telescopic sections means for causing said sections to rotate together, one section of said spindle being adjustable axially, weighted arms connected with said spindle a rotating sleeve mounted on the standard and means connecting the sleeve and longitudinally movable section of the spindle for moving the same longitudinally.

3. In a revolving governor, the combination with a rotating and longitudinally adjustable spindle, means for rotating same and weighted arms connected thereto, a collar secured to said spindle, a bearing on which the collar rests, and an internally threaded sleeve engaging threaded members on the bearing for moving same vertically.

4. The combination of a tubular standard, a rotary and longitudinally adjustable spindle therein. a sleeve on the spindle, weighted arms connected to the spindle and sleeve, an d means connecting the sleeve and lugs on the sleeve engaging slots in the standard, of a collar secured to the spindle, a bearing for said collar and an internally threaded sleeve carried by the standard and engaging threads on projecting members on the bearing.

5. In a rotary governor, the combination with a longitudinally movable spindle and weighted arms connected therewith, of a bearing for the lower end of said spindle, through which the spindle passes, a collar on the spindle cooperating with said bearing, and means for moving said bearing to adjust the spindle longitudinally.

6. In a rotary governor, the combination with a longitudinally movable rod and weighted arms thereon, of an adjusting hearing through which the rod passes, a collar fixed to the rod and spaced by rollers from the bearing, and an internally screwthreaded sleeve engaging said bearing for adjusting same vertically.

7. The combination with atubular frame or casing, of a longitudinally movable spindle therein, a bearing embracing the spindle, a collar on the rod spaced from the bearing by anti-friction rollers, threaded lugs on the bearing located in slots in the frame or cas ing, an internally threaded sleeve on the easing meshing with the threaded lugs, and a hand wheel on said last-mentioned sleeve.-

8. In a governor, the combination with a longitudinally movable spindle having a tubular lower end and weighted arms connected with said spindle, of a drive rod terminating at its upper end within the tubular lower end of the spindle, a key in the spindle en gaging a slot in the drive rod and manuallyoperated means for moving the spindle longitudinally relatively to the drive rod.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
